Nectarine Tree Named &#39;NJN101&#39;

ABSTRACT

A new and distinct nectarine variety of  Prunus persica  named ‘NJN101’ is provided. This variety is distinguished from other nectarine varieties by its unique combination of showy flowers, fruit that ripen in early-season, glossy fruit with an attractive red over color and orange red ground color, clingstone fruit with a juicy, melting texture and sweet, moderately acidic flavor, and excellent production of firm fruit that maintain their eating quality following cold storage.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of nectarine tree named ‘NJN101’. Our new tree resulted from crossing ‘B8-9-46-712034’ as the seed parent with ‘Eastern Glo’ nectarine tree, as the pollen parent. The new variety differs from seed parent ‘B8-9-46-712034’ (unpatented) in that the new variety has large, showy flowers and firm, yellow-orange fleshed fruit with an attractive, glossy finish, while the seed parent has small, non-showy flowers and comparatively soft, greyed-white fleshed fruit that usually have a poor finish. The new variety differs from pollen parent ‘Eastern Glo’ (U.S. Plant Pat. No. 7,890) in that the new variety has been cold hardy to about −20° C. and has good eating quality, while the pollen parent has had light crops after exposure to −20° C. and generally has fair eating quality. The resulting tree was selected when growing in a cultivated area located at a fruit research center in Cream Ridge, N.J.

BRIEF SUMMARY OF THE INVENTION

The ‘NJN101’ variety is distinguished from other nectarine varieties due to the following unique combination of characteristics:

Round fruit with a low tendency to split for the season.

Glossy fruit with an attractive red over color and orange-red ground color.

Excellent production of firm fruit that ripen in early-season.

Fruit with a good to very good eating quality.

The variety was asexually reproduced at a fruit research center in Cream Ridge, N.J. Asexual reproduction of this new variety by budding onto>Lovell=rootstock (unpatented) shows that the foregoing characteristics are so reproduced.

The following detailed description concerns the original tree, ‘NJN101’. The original tree and asexual progeny have been observed growing in a cultivated area at the fruit research center in Cream Ridge, N.J. Certain characteristics of this variety, such as growth and color, may change with changing environmental conditions (such as, light, temperature, moisture, nutrient availability) or other factors. Color descriptions and other terminology are used in accordance with their ordinary dictionary descriptions, unless the context clearly indicates otherwise. Color designations are made with reference to The Royal Horticultural Society (R.H.S.) Colour Chart. (1966 Edition)

BRIEF DESCRIPTION OF THE DRAWINGS

This new variety is illustrated by the accompanying photographic drawings, depicting the nectarine tree by the best possible color representation using color photography. Colors are approximate as color depends on horticultural practices, such as light level, fertilization rate, and other conditions and, therefore, the color characteristics of this new variety should be determined with reference to the observations described herein, rather than from these illustrations alone.

FIG. 1 is a color photograph taken on Jun. 14, 2011 of a characteristic twig of ‘NJN100’ in the late spring bearing typical leaves of the foliage.

FIG. 2 is a color photograph taken on Jul. 16, 2004 of characteristic mature fruit and stones of ‘NJN101’. Whole fruit are presented in three positions and a transverse cross section to show that the pericarp tends to adhere to the pit when the fruit is mature. The stones illustrate the ovate shape and the pit grooves on the surface of the stone.

FIG. 3 is a color photograph of a characteristic twig that illustrates the typical flower buds and large, showy flowers of ‘NJN101’ observed on a tree that was 6 years of age on Apr. 21, 2004.

FIG. 4 is a color photograph of a dormant tree of ‘NJN101’, prior to pruning, in late winter that illustrates the rounded, slightly upright growth habit of a tree at the fruit research center in Cream Ridge, N.J. on Feb. 17, 2011.

FIG. 5 is a color photograph taken on Feb. 17, 2011 of immature bark of ‘NJN101’ that illustrates color and the moderately high density of conspicuous lenticels on the immature bark.

FIG. 6 is a color photograph taken on Feb. 17, 2011 of mature bark of ‘NJN101’ that illustrates the moderately smooth texture and conspicuous elliptical lenticels of the mature bark.

The colors and illustration of this type may vary with lighting and other conditions and, therefore, color characteristics of this new variety should be determined with reference to the observations described herein, rather than from these illustrations alone.
